Description
Technical field
The present invention relates to a kind of push-pull valve, particularly relate to a kind of push-pull valve for controlling high-temperature dust-containing flue gas pipeline break-make.
Background technology
At present in high-temperature flue gas UTILIZATION OF VESIDUAL HEAT IN and high-temperature flue gas environment protection treating, it is required for the break-make that flue plugboard valve is set to control high-temperature dust-containing flue gas pipeline. Owing to high-temperature flue gas containing dust, especially when adhesiveness is strong dust is more, make no matter existing push-pull valve is on or off state, capital has in the guide groove and kerve that substantial amounts of dust is collected in valve casing, when dirt accumulation height exceedes the gap value between plate bottom and kerve, plate will be unable to arrive lower position, and YE can not get lower position signal, torsion will be continued to increase, until motor overload even motor damage. Additionally due to the sealing between screw mandrel and valve casing is packing seal, when screw mandrel enters in valve casing, it is exposed in flue gas, a large amount of dust will be gathered in the screw thread of this section of screw mandrel, once screw mandrel screws out valve casing, the airtight and watertight padding that will wear and tear rapidly between screw mandrel and valve casing, flue gas is caused to leak outside.
Goal of the invention
It is an object of the invention to solve the above drawback of the flue plugboard valve existence under prior art, and provide a kind of anti-executor of anti-laying dust to cross the high-temperature flue sealing plug-in board valve that placing flue gas is revealed.
It is an object of the invention to be achieved by the following technical programs:
A kind of high-temperature flue sealing plug-in board valve, including valve casing and plate thereof, valve casing both sides are provided with enter corresponding with plate, go out floss hole, valve casing top is provided with bracing frame, bracing frame is provided with YE, the clutch end of YE is connected with screw mandrel, the bearing block that it is characterized in that screw mandrel end and be located at valve casing top is connected, screw mandrel is provided with push pedal, push pedal center is provided with the feed screw nut being connected with screw mandrel, the push pedal symmetric position of feed screw nut both sides is respectively provided with a push rod, push rod one end connects fixing by locking nut, the traverse push pedal of its other end, in insertion valve casing, and be connected with the top of plate, described valve casing in floss hole, be equipped with the guide rod that axis vertical is downward, be slidably matched with the corresponding side of plate by guide rod, guide rod two ends are fixing with floss hole respectively to be connected.
On the basis of technique scheme, the present invention can also have technical scheme further below.
Described valve casing top symmetric position is respectively provided with an adapter sleeve being slidably matched with push rod cylindrical, be fixedly connected on valve casing bottom adapter sleeve, top is provided with end cover, it is provided with airtight and watertight padding, by utilizing gland sealed mode to avoid flue gas to leak out between adapter sleeve and push rod between described adapter sleeve and push rod.
Push rod bottom described push pedal and between valve casing top is provided with annular boss; annular boss is provided with the spring being sleeved on push rod; spring one end contacts with annular boss; its other end and push pedal base contact; when in valve casing, the flue dust of deposition reaches to a certain degree; plate and push rod cannot drop to appointment lower position; now so that plate still can continue to come downwards to appointment lower position under the elastic reaction of spring; so that YE obtains out-of-work signal, thus protecting YE.
Described push pedal top symmetric position is respectively provided with dust cap, is covered push rod one end by dust cap, to prevent dust and rainwater from dropping on push rod and locking nut thereof.
Described push pedal bottom symmetrical position is respectively provided with dust-proof sleeve, is entangled by the push rod between bottom annular boss and push pedal by dust-proof sleeve, to prevent dust and rainwater from dropping on the push rod between bottom push pedal and on spring.
The beneficial effects of the present invention is simple in construction, reliability is high, leaks outside reducing flue gas, while environmental pollution, also improves the utilization rate of high-temperature flue gas, reduce the maintenance rate of equipment.
Below just accompanying drawings and embodiment the present invention is further described.
